Detailsinfo

A vulnerability was found in cjbassi gotop 3.0.0. It has been rated as problematic. Affected by this issue is an unknown code of the component Process Termination. The manipulation with an unknown input leads to a argument injection vulnerability. Using CWE to declare the problem leads to CWE-88. The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. Impacted is integrity, and availability. CVE summarizes:

cjbassi/gotop is vulnerable to local argument injection via process termination functionality. The process name is passed directly to pkill without sanitization. A local attacker can create a process with a crafted name beginning with -- (e.g. containing a target user's UID). When the user running gotop invokes the kill feature on that process, pkill interprets the crafted name as a command-line option, terminating all processes owned by the targeted user. Product is no longer actively supported and the vulnerabilities have not been fixed. Vulnerability was confirmed at version 3.0.0; other versions were not tested but may also be affected.

The advisory is available at cert.pl. This vulnerability is handled as CVE-2026-91784 since 09/15/2026. The exploitation is known to be easy. Local access is required to approach this attack.
